Help! Wiring Diagram Jacobs Brake

[THaslett]

Trying to install Jacobs retrofit switch kit in place of the pacbrake flip switch on my 06. I need a wiring diagram to show where to run the black and red wires in the loom. Yellow to pin 39 like the pacbrake, black eyelet connector to ground. Jacobs instructions are horrible. Cummins Part # of wiring/switch kit is 4920060, Dodge part #037525. THANKS

Not certain if the switch you're trying to install is the '07 & newer switch or not. If it is, you're in for a real challenge getting it to work. The problem is the new switch is momentary contact and the '06 wiring and computer requires a positive on/off. With help I finally got it operating using a PAC TR7 module and a relay but it just didn't function the way I wanted. I finally installed a Radio Shack switch and have been very happy with it. For a pic and diagram, see my post of 1-8-2008.
